While updating to 7.1.0 (from 6.x) I got the following error in my project:

* What went wrong:
A problem occurred configuring project ':shared'.
> Cannot query the value of task ':shared:jvmRun' property 'mainClass' because it has no value available

Upon investigation, it appears that kvision now assumes the existence of a jvmRun with a mainClass property (https://github.com/rjaros/kvision/blob/master/kvision-tools/kvision-gradle-plugin/src/main/kotlin/io/kvision/gradle/KVisionPlugin.kt#L296).

However, my project structure is as follows:
• shared -- has kvision plugin, but no application plugin -- this is a library so there is no mainClass
• backend -- has application plugin, and therefore has a mainClass
• client
@Robert Jaros what do you think? Can we add a config setting on the kvision plugin to not provide any jar functionality? I take care of this on my own.
